There has been a rapid expansion in the development and description of both quantitative and soft system methods that can be applied to decision - making processes and many of these have application in the spatial domain 已经有发展和能被适用于决策的程序的数量的和软性系统方法的描述的迅速的扩充,而且多数的这些在空间的领域中有申请。
In the image quantization and enhancement section , the non - linear gray mapping based on histogram specification and the enhancement digital filter in spatial domain is applied to the result digital subtraction images 对于获得的数字剪影结果图象采用了规定化直方图的非线性灰度变换算法,同时对于结果图象的增强设计了空域数字滤波器。
In the case that there exist great differences among the registered images , the higher performance is proved in the comparison experiments with the current image registration algorithms which base on feather in spatial domain 该算法针对sar图象与多光谱图象差异性较大的特点,采用图象边缘的线性不变矩作为特征矢量进行遥感图象配准。
The main content of this dissertation are as follow : 1 , the author analyses and derives the statistics characteristic of speckle , including the statistics characteristics for speckle of the intensity and amplitude images in the spatial domain 本文的主要内容为: 1 、分析了相干斑的统计特性、包括空间域的强度和幅度图像的相干斑统计。
Like other transforms such as dct and wt , zh - transform can transform the image data from spatial domain to another frequency - like domain , and zh - transformed data can describe the shape from coarser to finer 类似于dct和wt等变换, zh变换可以把图像数据从空间域变换到另一个类似于频率域的域,使变换后的数据从粗到精地描述了视频对象地形状。
